- New OSS/3D Fidelity Enhance feature added to Virtual Mixer PRO. 4Front's Fidelity Enhance allows you to playback music, watch DVDs, play games and enhance the audio quality in ways you will never imagine that this could be done on Linux.

OSS v3.99b is beta and all time out restrictions are removed. This version will still nag you by playing some "star wars" like sounds after 3 hours but only when the device is idle. For all practical purposes it's "free beer".
